About Us


Mervin Zimmerman founded this company in 1968, starting out with a little red pickup truck and using the family barn as his base of operations. He focused on providing quality plumbing, heating and air conditioning services to residential customers in the local area.

From the beginning, Mervin had a vision of a retail store and showroom where customers could come to see products, get parts and receive advice. From this vision, The Bath Barn was born. Over the years, Mervin Zimmerman Inc. emerged as a leader in custom bath remodeling and continued to provide plumbing, heating and air conditioning service to residential and light commercial customers.

Today, our retail store & showroom features bathroom designs, along with hundreds of bathroom products on display to help our customers visualize their dream bathrooms and make that vision a reality within their ideal budget.
